Charley - if you can get to Hull a little earlier in the day you can visit Hull Maritime Museum (between the Rail/Bus Station and the Black Boy and it's free entry) or the Arctic Corsair which is berthed quite close to the Black Boy and Wednesday is one of the days it's open to the public. There is a small charge but it's a conducted tour. If you want either of these options I'll be happy to meet up and be an additional guide.
